Tens and Ones Build Worksheet

Kids often count teen numbers correctly, then stall when asked what the digits mean. This one-page activity keeps the focus small and clear: build 18, 19, and 11 by showing one ten and the correct number of ones, then use the writing fields to record the tens and ones.

This is a good fit when a child can count past 20 but is still shaky with place value language. The page gives a simple model for each number, so you can point to the ten first, then count the extra ones together. If counting objects still feels easier than written numbers, the circle counting and drawing worksheet gives extra practice with matching a counted set to a number.

The practice works by slowing down each teen number. For 18, 19, and 11, children read the whole number, notice the tens part, count the ones part, and write what they see. That repeated pattern helps them connect the written number to tens and ones instead of treating teen numbers as random shapes to memorize.

Sit nearby and ask simple questions like, “How many tens do you see?” and “How many ones are left?” If an answer is off, have your child recount the ones before writing. For a next step, use the number cards one to twenty worksheet to read, order, and compare numbers around 11, 18, and 19 after the place-value work is done.
